NIDA Clinical Trial Requesting Volunteers for Learning Tasks

You may be eligible for a research study.


The National Institute on Drug Abuse (NIDA) is looking for volunteers to participate in a study which seeks to find out if performance in learning specific tasks differs in people who have an opioid-use disorder and those who don’t. This study requires one lab visit which would last around five hours.


Eligibility for the study:

  • Between ages of 21 and 60

  • Willing to fast at least six hours prior to the session and smell food odors

  • If you have an opioid-use disorder

  • Be abstinent for three weeks or

  • Be in methadone or buprenorphine treatment

  • Can’t be intoxicated at the time of session

  • Can’t be pregnant


Layout of the study:

  • Participants will give a urine and breath test.

  • Participants will be given tests of learning such as looking at a computer screen with shapes which are paired with food odors. Afterwards participants will be given a shape and asked which odor to expect.

  • 30 and 60 days later, participants will be called and asked about their drug use over the last 30 days.
